Lex Fridman uses so much the word “humans” as opposed to “people” that I’m starting to think he may be an alien.

Someone has sure already made this observation but the fact they can convert all those empty warehouses into prison camps means they could have converted them into housing, community centers, job training centers or, hell, libraries or schools all along. It’s always a matter of will not resources.

Short musings on "cognitive debt" - I'm seeing this in my own work, where excessive unreviewed AI-generated code leads me to lose a firm mental model of what I've built, which then makes it harder to confidently make future decisions simonwillison.net/2026/Feb/15/...
How Generative and Agentic AI Shift Concern from Technical Debt to Cognitive Debt

AI is a bubble, but too many people confuse a bad investment strategy with the tech itself. AI will not go away after the bubble bursts any more than websites went away after the dot-com crash. The tech is too useful (though not the panacea the hype mongers would have us believe).

I find AI makes work isolating.

Instead of asking "Jeff" about something, I ask chat GPT. I miss out on the team cohesion aspect and opportunities for cross pollination of info.

Chat GPT will tell me how to use (service) to accomplish (goal), Jeff might have a different approach entirely.

The Sánchez 🇪🇸 government has

- built Europe's boom economy
- hiked minimum wage from €736 to €1221
- cut insecure work from c.30% to c.13%
- regularised, not demonised, migrants
- stood up for human rights
- refused to humiliate itself before Trump

No wonder Musk hates it.

Demanding an estimate guarantees the estimate will not be useful to the business and will always drive costs up.

Software engineers all know that estimates are useless.

State of JS 2025 is out. It’s interesting how negative sentiment @nextjs.org generates year by year. Undeniable winner is @vite.dev, and its growing ecosystem... of course. 😍

"All over the world, wherever there are capitalists, freedom of the press means freedom to buy up newspapers, to buy writers, to bribe, buy and fake 'public opinion' for the benefit of the bourgeoisie.

This is a fact.

No one will ever be able to refute it."

Thoughts from using Claude Code for two days as a non-programmer
- This is absolutely incredible
- This doesn’t seem fair
- We, as a world, need UBI ASAP.
